The Cisco® 2000U Industrial Ethernet Switches (IE 2000U) are a range of compact switches designed for the harsh, rugged environments often found in the energy and utility industries. IE 2000U switches are designed to support the communications infrastructure needs for the energy delivery infrastructure across distributed generation, transmission, and distribution sectors. This infrastructure includes utility- and customer-owned energy infrastructure, such as substation applications supporting electrical transmission and distribution, renewable generation, oil and gas, water, distributed generation, cogeneration, and trackside operations. The infrastructure also includes communications infrastructure for delivery applications such as transmission pipelines, distribution mains, and service lines for oil and gas and water.
